what type of legal header is best?

hey, im looking into aftermarket headers for an 03 zx3 with 16v zetec engine, was just wondering everyones input on which are the best. Im curenttly living in ontario, canada which have emission standers but were changing to the new test that will read your carís computer history to see if your vehicle meets emissions standards. does that mean i could get a one piece header cause ive heard theres more gain out of them then short headers? But if i do get anykind of header do i also have to change my cat and flex pipe to aftermarket? cause ive heard it could up your cat n flex pipe because of the increase air flow. i am currently running a magnaflow 2.25 in exhaust so im good with that.
